available alternatives the sector will turn to more conventional methods in order to achieve the growth that the market demands, thus compromising its identity. In the light of this, it is vital that the sector continues to invest in its own qualitative development. There is currently much debate about the course of the organic agri-ecological system and the type of breeding that would best
As a general rule, conventional breeding develops new plant varieties by the process of selection , and seeks to achieve expression of genetic material which is already present within a species.

Plant breeding can be broadly defined as alterations caused in plants as a result of their use by humans, ranging from unintentional changes resulting from the advent of agriculture to the application of molecular tools for precision breeding. The vast diversity of breeding methods can be simplified into three categories: (i) plant breeding
From a breeding perspective, once a plant is stably transformed, i.e., has undergone several generations of selfing, and is shown to pass the trait on to its progeny, the trait is treated as qualitatively inherited and used as such in any breeding method.

There are three wass whereby unconventional methods of plant genetics can be used for applied plant breeding. 1. The time necessary for breeding by recombination can be shortened, making use of the discovery that plants can be obtained directly from the products of meiosis, the “Gonen.” Two new

variety of conventional breeding or newer techniques. The boundaries between established genetic modification(GM) and non-GM techniques will become increasingly blurred as techniques develop. • This raises questions about how new crop varieties should be regulated. A regulatory system based on the characteristics of a novel crop, by whatever method it has been produced, would provide more
The easiest method of plant genetic modification (see Operational Definitions in Chapter 1), used by our nomadic ancestors and continuing today, is simple selection.

In this article we will discuss about the biotechnology in plant breeding. In the conventional plant breeding programme, the development of a new variety or hybrid takes about five to twelve years, starting from inbred production and then hybridization and selection of F 1 hybrids.
Conventional plant breeding has been the method used to develop new varieties of crops for hundreds of years However, conventional plant breeding can no longer sustain the global demand with the Increasing population, Decline in agricultural resources such as land and water, and the Decreasing of the yield curve of the staple crops Thus, new crop improvement technologies should be developed
With conventional breeding techniques, plant breeders can combine two unique plants within the same species (one cotton plant with another cotton plant) in hopes of getting something that combines the best of those two plants into something new.
organism by a diverse technique like physical, chemical and biological methods. Transgenic plants are obtained by introducing a gene into its genome with the help of vectors in order to develop a plant with new characteristics.

Conventional plant breeding has been going on for 10’s of thousands of years and still continues and gives us more new varieties than any other method. Nicolai Vavilov a famous Russian plant breeder and geneteticist made in the early 1900’s what is still the worlds largest and most comprehensive seed collection that still exists today. He used this collection to breed many of the varieties
Traditional plant breeding Through cross breeding existing varieties, the breeder aims to re-shuffle the plants’ genetic material to produce new varieties that may have useful characteristics. Approx 40% of the genetic material is reorganised in the resulting hybrid plant.
